Abstract

Selection of chickpea (Cicer arietinum L.) cultivars with wide adaptability across diverse farming environments is important before recommending them to achieve a high rate of cultivar adoption. Multienvironment trials including 3 years and 5 locations for 17 genotypes of autumn chickpea were carried out in Iran. Additive main effect and multiplicative interaction (AMMI) were used to understand the GE interaction pattern. Analysis of variance of grain yield showed that 68.36% of the total sum of squares was attributable to environmental effects, only 15.9% to genotypic effects and 13.55% to GE interaction effects. Biplot of the first principal component and mean grain yields for genotypes and environments revealed that high yielding genotypes were not stable cultivars regarding final yield. The AMMI2 mega-environment analysis identified four chickpea megaenvironments in Iran. The first megaenvironment contained locations, Ghachsaran and Lorestan, where genotype Arman was the winner; the second megaenvironment contained locations Gorgan, where genotype FLIP 98-126C was superior. The tertiary megaenvironment contained locations in Ilam, where genotype FLIP 98-82C was superior and the location of Kermanshah made up the other megaenvironment, with FLIP 98-201C as superior.

Highlights

Legumes have been considered a rich source of protein throughout the world and contain approximately three times more proteins than cereals
The objectives of this study are to (i) interpret G main effect and genotype × environment (GE) interaction obtained by Additive main effect and multiplicative interaction (AMMI) analysis, (ii) use the AMMI megaenvironment analysis to examine the possible existence of different megaenvironments in chickpeagrowing regions in Iran
The analysis of variance of grain yield of the 17 genotypes tested in fifteen environments showed that 68.36% of the total sum of squares was attributable to environmental effects, only 9.23% to genotypic effects, and 22.41% to GE interaction effects (Table 3)

Summary

Introduction

Legumes have been considered a rich source of protein throughout the world and contain approximately three times more proteins than cereals. Legumes and specially chickpea (Cicer arietinum L.) are important sustainable production of food in the arid and semiarid countries of west Asia such as Iran. Major producing countries include India, Pakistan, and Iran [1], where the crop is generally planted after the main rainy season and grown on stored soil moisture making terminal drought stress a primary constraint to productivity. Northwest and northeast of Iran are favorable for the production of Kabuli chickpea. Food legume and specially chickpea in Iran accounts nearly 1.32% of the world pulses area and 0.9% of the world production [2]. Successful new genotypes must show high performance for yield and other essential agronomic traits. Chickpea cultivars must show high performance for yield and other essential agronomic traits
